Question

What is the magnitude of the vector = <4, 7>?

Answer 1

`√(65) = 8.06`

Explanation:

Assuming u = <4, 7> then the coordinates of the vector are 4 and 7, then we must apply the magnitude formula.

`\sqrt{4^(2) + 7^(2) } =√(16 + 49) = √(6\\5)`

So, the answer is 8.06 (if you round to hundredths place... if more is required simply insert
`√(65\\)` into your calculator).
